The moment of inertia of an object is a property that describes how difficult it is to rotate the object about an axis. Rotational inertia accounts for the stability of gyroscopes and bike-riders, and has applications for navigation of planes and figure skaters performing lightning-fast spins. Richard Garriott experiments with spinning a deck of playing cards to demonstrate both stable rotation and tumbling rotation.
